How Plants Grow
Plants are essential to life on earth.
They are the first step in the food chain, which -- as you probably remember -- goes like this:
The Food Chain
- Plants take energy from the sun and turn it into food for themselves -- and for the animals that eat them. (Animals that eat plants are called herbivores.)
- Herbivores (cows, horses, rabbits, etc.) eat the plants.
- Carnivores (animals that eat other animals) eat the herbivores. Cats, dogs, wolves, vultures, eagles and tigers are carnivores. (Human beings are omnivores -- which means that we can eat both plants and animals.)
- Finally, decomposers (bacteria, fungus and tiny creatures like maggots) devour leftover dead plants and animals. They are like a clean-up service for the environment.
Plants turn sunlight into food through a remarkable process called photosynthesis, which we'll tell you about in our next lesson.
